UT123D
Smart Digital Multimeter Manual
1.Overview
UT123D is a smart digital multimeter,it can automatically identifythe function and range to improvethe operation efficiency.EBTN screen enables userto get a clear reading even working in darkenvironments.This product conforms to CE safety standard,which ensures users’safetywhenoperating inCAT II 600V environment.Its unique appearance and compact design makes it a greattool for home and DIY applications.
2.Features
1)Automatically detect power level at start up,green light means normal while red light and buzzer beep means power level is low.
2)Automatically identify input signals(resistance,DC/AC voltage and current).
5)On LVE mode,distinguish between neutral and live wire via light color and buzzer. 6)Maximum voltage is 600V,with over voltage/current alarms
7)Large capacitance measurement (4mF) 8)EBTN display
Please carefully read “Safety instructions”and”Attention”sections in this manual.
3.Accessories
Open the box and check whether the meter and the following items are missing or damaged:
1)Userr manual– –1 piece
4.Safety instructions
Please pay attention to “Attention”notices below.Warming means it may pose hazard to users,
and may damage the meter or device.This multimeter meet with EN61010-2-030/61010-2-033,
EN61326-1 safety standard of ectromagnetic radiation protectio and meet with safety standard
1)Before use,please check the meter and probe to make sure there is no any damageor abnormity. If the meter orprobe is significantlydamaged,orif you thinkthemeter cannot function properly,
r housing or battery housirng is not covered up,otherwise it might he finger guard ring of the probe,
do not touch exposed wire,connectors,terminals,circuit.
When measuring,never change the range setting to avoid damage to the meter!
Do not apply voltage over 600V between any meter teminaland earth ground to prevent electric
7) Only measure the voltage/curent that are within the specified limit.Disconnect with all power source and fully discharge the capacitor power before measuring resistor,diode or circuit
otherwise the measurement accuracy might be affected.
8)When the”O”symbol appears on the LCD,please replace the batteries in time to ensure the measurement accuracy.Take out the batteries ifthe meter is not in use fora long time
9)Do not change the intenal circuit of the meter to avoid damage to the meter anduser!
